如何使用geoplugin在php中获取国家名称？

Question

你好，我被困在这，我不知道发生了什么。 我正在使用google geo插件api通过IP地址获取国家/地区名称。 这是我的代码如下：-

$client  = @$_SERVER['HTTP_CLIENT_IP'];
$forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote  = @$_SERVER['REMOTE_ADDR'];
$result  = array('country'=>'', 'city'=>'');
if(filter_var($client, FILTER_VALIDATE_IP)){
    $ip = $client;
}elseif(filter_var($forward, FILTER_VALIDATE_IP)){
    $ip = $forward;
}else{
    $ip = $remote;
}
$ip_data = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=".$ip));    
if($ip_data && $ip_data->geoplugin_countryName != null){
    $result['country'] = $ip_data->geoplugin_countryCode;
    $result['city'] = $ip_data->geoplugin_city;
}
echo "<pre>"; print_r($result); die;

我来自印度。 有时，当我访问显示印度的网站或显示新加坡的某个时间时。 但是我仅位于印度。 谁能建议我们我做错了什么，并提供其他选择，以便我们获得正确的结果。

可能是因为您正在检索ip。 您可以使用以下方法获取客户的IP地址：

function get_client_ip() {
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
    $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
    $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
    $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
    $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
    $ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
    $ipaddress = $_SERVER['REMOTE_ADDR'];
else
    $ipaddress = 'UNKNOWN';
return $ipaddress;
}

然后使用您收到的IP查找国家名称：

function ip_info($ip = NULL, $purpose = "location", $deep_detect = TRUE) {
$output = NULL;
if (filter_var($ip, FILTER_VALIDATE_IP) === FALSE) {
    $ip = $_SERVER["REMOTE_ADDR"];
    if ($deep_detect) {
        if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
            $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
        if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
            $ip = $_SERVER['HTTP_CLIENT_IP'];
    }
}
$purpose    = str_replace(array("name", "\n", "\t", " ", "-", "_"), NULL, strtolower(trim($purpose)));
$support    = array("country", "countrycode", "state", "region", "city", "location", "address");
$continents = array(
    "AF" => "Africa",
    "AN" => "Antarctica",
    "AS" => "Asia",
    "EU" => "Europe",
    "OC" => "Australia (Oceania)",
    "NA" => "North America",
    "SA" => "South America"
);
if (filter_var($ip, FILTER_VALIDATE_IP) && in_array($purpose, $support)) {
    $ipdat = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip));
    if (@strlen(trim($ipdat->geoplugin_countryCode)) == 2) {
        switch ($purpose) {
            case "location":
                $output = array(
                    "city"           => @$ipdat->geoplugin_city,
                    "state"          => @$ipdat->geoplugin_regionName,
                    "country"        => @$ipdat->geoplugin_countryName,
                    "country_code"   => @$ipdat->geoplugin_countryCode,
                    "continent"      => @$continents[strtoupper($ipdat->geoplugin_continentCode)],
                    "continent_code" => @$ipdat->geoplugin_continentCode
                );
                break;
            case "address":
                $address = array($ipdat->geoplugin_countryName);
                if (@strlen($ipdat->geoplugin_regionName) >= 1)
                    $address[] = $ipdat->geoplugin_regionName;
                if (@strlen($ipdat->geoplugin_city) >= 1)
                    $address[] = $ipdat->geoplugin_city;
                $output = implode(", ", array_reverse($address));
                break;
            case "city":
                $output = @$ipdat->geoplugin_city;
                break;
            case "state":
                $output = @$ipdat->geoplugin_regionName;
                break;
            case "region":
                $output = @$ipdat->geoplugin_regionName;
                break;
            case "country":
                $output = @$ipdat->geoplugin_countryName;
                break;
            case "countrycode":
                $output = @$ipdat->geoplugin_countryCode;
                break;
        }
    }
}
return $output;

}

有时您可能无法使用我之前提到的功能来获取客户端ip，在这种情况下，就像您曾经使用过的那样，您可以使用以下方式获取其客户端的公共ip：

file_get_contents("http://ipecho.net/plain")

然后使用收到的公共IP再次调用ip_info函数。
